Method for selecting system in a mobile terminal

Abstract

A method for selecting a system in a mobile terminal is disclosed. The method includes upon power-up of the mobile terminal, reading system information included in a Most Recently Used (MRU) table from memory, and registering the system information in a variable area of a system search table; reading system information from a Preferred Roaming List Acquisition (PRL ACQ) table stored in the memory, and registering the system information in a fixed area of the system search table; and performing system search based on the system search table.

Description

PRIORITY [0001] This application claims priority under 35 U.S.C. § 119(a) to a Korean Patent Application filed in the Korean Intellectual Property Office on Mar. 9, 2006 and assigned Serial No. 2006-22388, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to a method for accessing a mobile communication system by a mobile terminal, and in particular, to a method for selecting a system by a mobile terminal. [0004] 2. Description of the Related Art [0005] To cope with the rapid development of mobile communication systems and the large increase in the amount of data being serviced in the mobile communication systems, 3rd Generation (3G) mobile communication systems with the necessary throughput for transmitting the increased amount of data at higher speed have been developed. For the 3G mobile communication systems, Europe has adopted asynchronous Wideband-Code Divisio...

Benefits of technology

[0031] An aspect of the present invention is to address at least the above described problems and / or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present invention is to provide a system selection method in which a mobile terminal efficiently configures a system search table used for system selection, and selects a system using the system search table, thereby stably providing a mobile communication service.

[0032] Another aspect of the present invention is to provide a system selection method in which a mobile terminal configures a system search table provided for system selection such that it can freely make addition and extension of areas, thereby facilitating general-purpose system selection.

[0033] A further aspect of the present invention is to provide a system selection method in a mobile terminal, which registers various search scenarios in a system search table configured for system selection, thereby facilitating efficient system selection.

Problems solved by technology

In addition, when the developer desires to change the search order of the system scan list, he / she should know all processes for configuring the system scan list, making it difficult to change the search order.
